' IMPROVEMENT IN JOURNAL-BOX.

TO ALLYWHOM IT MAYCONERN:

Be it known that I, JAMES T.VR0BIE'IT, of Petersburg, in the county of Dinn'iddie, andState ot' Virginia., here invented a. new and improverlJonrnal-Box; and I do hereby declare thnt'the following is a t`ullclear,lnnd` exect description of' the construct-ion and operation of the samefreference being hnd to the annex-.ed lrnwings', making a. part of this specification, in which- Figure '1 is a'crossfsection. v

FignreZ-is n. topview. l

This invention relates to an improvement in that class ,ot`l` bearing-pieces employed inca-rmxle boxes, or other bearings for any machinery, in which'the body vof the bearing-piece is of iron, the moin portion o'fi'the convex surface beingof Babbit o r any anti-friction', metal, and the central portio'n being of brass. f i

The -improvement consistsin a new method of attaching the brass central plate; to the iron body o ,tifth'e bearingpieee, Vwhereby thc former- .will be more .securely held inpositon, and prevented from' working; out or being thrown ont by any accident.l l v In the drawings, A represents'the iron, brass, or composition body of the bearing-piece, B beingthe conca-ve bearing-surface, of Babbit, ornther anti-friction metal, attached thereto in the usuelmnnner,- and G being the central plate, oflbrass, Ashovm-in section in iig.' l, and in outline by the dotted lines of. iig. 2. i

This `plate is provided at or near each end with n boss onteat, D, which extends through'the iron-piecef A, and isp'rovided witha longitudinal channel or opening, E, theinner end of whichcommunicates with the surface of the-axle, while the outer enti communicates with-the reservoirs of lnbricnting-materinl, L L, above the bearing-pece i v As 'thus for described, I mewarejthat this same construction has heretofore been tn nployed for asimilar `s :'PUIPOSG' .Y

` i My improvement consists in the method by which I x the plate, D, tothe iron, brass, or other composivtion 'piece A, in order to prevent them from becoming detached, as nbo've set forth. To this end, I cast the sockets in the iron piece which receive' the tests, DD, with expanded or funnel-form extremities, on the rear or upper side of the iron'p'iece,lA, and, after inserting the brass plate in its pince, the tents entering"y the sockets provi-dedfor4 them, andlthcirends coming to the rear edge of,A the part A, orto the bottom of the reservoir LLIA upset theupper4 end ot" the tents, orpre'ss them outward against the expandedwall of the socket, imparting` permanently to the teats o funnel-shape', as seen in figs. 1l and 2, andconning them-securely in their place. .Hoving thus described my invention, what I claim :ts new, and desire to secure by Letters -Potent, is-

The method of attaching thebrase plate C to the iron piece A, asherein set forth.'
